Is it possible to integrate High Charts with BPMN JS Viewer

I have added a pie chart icon in the palette. I am able to drag and drop pie chart into the canvas and set the values.

In the viewer, I wanted to display the pie chart based on values. Is it possible to integrate High Charts in BPMN Viewer

What does the pie chart represent in the context of BPMN? How do you save it in the resulting BPMN XML?
